Can't find instanced meshes that won't build lighting

I’m not sure what I did to cause this, but all of a sudden I have 10 objects that continue to have unbuilt lighting even immediately after rebuilding lighting. I ran DumpUnbuiltLightInteractions and they are all instanced foliage meshes. How exactly do I go about locating these 10 specific instances?

Alright, so I re-launched the editor, rebuilt lighting again, and now it seems to be working… I would still like to know how to locate a specific instanced mesh though.
